10 Claims.

This invention relates to a swinging sash mounting. More especially, our invention relates to a sash of the type which is adapted for first a vertical movement, and then a horizontal I swinging movement to an open position.

The invention is of especial utility in connection with interlocking sash of various types, both wood and metal, in which the relation of the sash to the frame is such that portions of each are interlocked to contribute a Weatherstripping effect. Thus, the sash in itself, by its relation to the frame, obviates the need of Weatherstripping because the window sash and the frame are in the same relation as usual commercial weatherstripping.

In a structure of this type, in order to swing the sash horizontally relatively to the frame from a closed to an open position, it is necessary to move it vertically first to release the sash from gointerlocking relationship with the frame, after which the sash may swing freely. Fixtures and hinges of many types have been developed in the art for this sort of structure, but none of these have achieved any real commercial success. While the combination which we shall disclose hereinafter is not broadly novel, since lifting and swinging sash mountings are old, yet it discloses a relatively broad improvement to the art, which art is of course confined to a very limited field. 30. As is frequently the case in inventions developed in a very narrow and highly developed field, a contribution which is seemingly of narrow scope really contributes to the art, many times, a relatively basic improvement, which is the last step toward the proper development of a commercial structure. We believe our contribution to be of this nature.

Before referring to the drawing for a detailed description of our invention, we should like to indicate generally some of the major improvements which we feel are embodied in our invention.

In general, our invention comprises the mounting of a window sash on a movable hinge portion adapted to move vertically, and then to rotate relatively to a fixed hinge portion. The movable hinge portion has preferably an extension on which is pivoted a handle having a'cam portion bearing on the pin of the hinge, which pin is 50. preferably fixed to the fixed hinge portion. The handle is so mounted, preferably, that when it is swung upwardly in the same direction in which the window sash is to be moved, its cam portion bearing on the pin will impart lifting movement 65; to the window sash in the axis of the hinge pin.

We feel that the movement of the window sash through effort applied in the axis of the hinge pin, and this in further combination with a lever adapted to be moved in the direction of the lifting of the window sash, is quite an important contribution.

Preferably, the fixed hinge pin of our invention is of considerable length relative to the movable hinge portion, which is in theform of a thin disk. Thus, the movable hinge portion always has full bearing on the hinge pin, which is in itself of considerable importance. Also, any friction which may be developed between the disk'and the hinge pin will be relatively slight because of the small bearing area between the hinge pin and the movable hinge portion. These features, we might indicate, are also of relatively great importance in this highly developed art.

A further feature of our invention residesin the use of the lifting lever handle for locking. the casement in a closed position or in a partially open position. Thus, the handle carries a lug which is adapted to rest in any one of a series of detent slots on the fixed hinge portion of our assembly. Movement of the handle in a direction to lift the window sash will first release the window sash and its movable hinge portion relatively to the fixed hinge portion, and this rereleasing will take place While the window sash is being elevated for release from its interlocking Weatherstripping association with the frame. Thereafter, the window sash may be rotated on the fixed hinge pin to a predetermined open position, and then lowered while the handle lug enters one of the detent slots for locking the sash in said predetermined open position.

Having thus described generally our invention, we shall now refer to the drawing and will describe a detailed embodiment of the invention.

In the drawing, Fig. 1 is a front view of a pair of swinging window sashes embodying my invention and showing one sash in a raised position and ready to be rotated. Fig. 2 is a section taken along line 22 of Fig. 1, and illustrates the interlocln'ng relation between the two windowsashes. Fig. 3 is a section taken along line 3-3 of Fig. 1. Fig. 4 is an elevation and partial section of my lower hinge and the handle used, therewith.

Referring now more particularly to the drawing, it should first be indicated that the case-, ments illustrated are of the structural steel type, although it is possible to utilize the invention where other materials, such as wood, are preferred. Each swinging window sash. l is mountterlocking engagement with its frame 2 and then rotated to a particular open position.

The upper hinge as illustrated in Fig. 3, comprises a movable hinge portion 5 secured to the movable sash, and a fixed hinge portion 6 secured to the frame 2. The fixed pin I is carried by the fixed hinge portion 6, and a nut 8 screw threaded on this pin limits the upward movement of the hinge portion 5, and therefore of the sash I relatively to the frame.

The lower hinge is shown in Figs. 2, 3, and 4, and comprises a fixed hinge portion I0 secured to the frame 2, and having a fixed hinge pin II secured thereto. The fixed hinge portion II) also has a series of detent slots I4, the use of which will be explained presently. Mounted on the fixed hinge pin II .is a disk 9 constituting the movable hinge portion, and adapted to be secured to the movable sash I for movement integrally therewith vertically relatively to the pin II, and also for rotation about the pin II.

Integral with the disk 9 is an extension on which is pivoted, through means of a pin I2, a lever handle l3 having a cam portion I3a in enclosing relation to the pin II. The cam portion I3 has 'a cam surface I3b in camming relation to pin II, so that as the lever handle is swung upwardly from its position in Fig. 4, the cam surface I31) will cooperate with the pin II to raise the disk 9 on the pin II, and thus elevate the sash I relatively to the frame 2 to the position of Fig. 1. This lifting will of course be imparted in the'axis of the pin l I, and it will be cffected by movement of the handle I3 in the direction of the lifting of the window frame I, as will be readily appreciated. This not only facilitates the lifting of the relatively heavy sash, but applies the lifting effort in a manner so as not to bind the hinges.

A locking lug I5 on the lever handle I3 is cooperable with the detent slots M of the lower hinge portion In, as shown in Fig. 4, to prevent rotation of the sash about thehinge pin II, and this relation of the lug I5 to:the detent slots I4 is adapted to hold the window sash in any rotated position, as will be clearly, understood by those skilled in the art. Also, for locking the window, the lever handle I3 may be equipped with. an'opening I6 cooperable with the opening I8 of a lug II carried by the window sash for securing the handle through means of a fastener, such as a padlock shackle.

We believe that the construction of our invention will now be apparent to those skilled in the art, and that its operation will be readily understood. While we have described a particular form of our invention, we wish to reiterate, that we consider this improvement to be broad within a narrow field, and we feel ourselves entitled to relatively broad claims, and to a relatively broad interpretation of those claims.
